Formula
Debt Yield = Net Operating Income ÷ Loan Amount
The course's own definition: it cites no published source.
- Net Operating Income (NOI)
- Income after operating expenses but before debt service and capital expenditure.
- Loan Amount
- The total first-mortgage principal, not the property's value or purchase price.
How it works
Debt yield exists because the other two underwriting ratios can both be manipulated by things that have nothing to do with the property. Loan-to-value depends on an appraised value, which is an opinion derived from a cap rate that moves with the market. DSCR depends on the interest rate and amortization schedule, so cheap debt or an interest-only period makes a weak property look safe. Debt yield removes both: it compares income directly against loan dollars, with no rate, no term, and no valuation in the calculation.
That independence is why the metric became standard after 2008. Lenders who had sized loans on optimistic values and low rates found that, when values fell and rates normalized, the loan balance was unsupportable by the income. Debt yield is a stress test with the stress already built in: it asks what the lender's return would be on day one of ownership, with no borrower and no financing assumptions in the way.
Read it as a yield on the loan. A 10% debt yield means that if the lender foreclosed and operated the property, it would recover its loan amount from net operating income in ten years, ignoring any resale. The higher the number, the less the lender has at risk relative to what the property actually produces.
Debt yield and cap rate together tell you which constraint binds. When the debt yield requirement is above the market cap rate, the loan is capped below the value-based limit and leverage falls, which is precisely what happens when rates rise and lenders push minimum debt yields up while cap rates lag behind.
Worked example
The same multifamily property produces $600,000 of net operating income and is valued at $9,000,000. The borrower requests a $6,500,000 loan. The lender's minimum debt yield is 9.0%.
| Step | Calculation | Result |
|---|---|---|
| Compute debt yield on the requested loan | $600,000 ÷ $6,500,000 | 9.23% |
| Compute the maximum loan at a 9.0% minimum | $600,000 ÷ 0.09 | $6,666,667 |
| Compare with the loan-to-value limit at 70% | $9,000,000 × 0.70 | $6,300,000 |
The request passes the debt yield test at 9.23% and could even support $6,666,667 on that measure alone. But the 70% loan-to-value limit caps proceeds at $6,300,000, and the 1.25x DSCR test computed above caps them at roughly $6,328,000. The lender lends the smallest of the three: $6,300,000. This is the central mechanic of loan sizing: the binding constraint is whichever test produces the least money, and it is rarely the one the borrower is watching.
Typical ranges
| Context | Typical minimum debt yield | Comment |
|---|---|---|
| Stabilized multifamily | 8% – 9% | Lowest thresholds in the market, reflecting income stability and agency liquidity. |
| CMBS conduit, stabilized commercial | 9% – 11% | Rating agencies effectively set the floor; this is where the metric is most rigidly applied. |
| Office and retail | 10% and above | Reflects rollover and re-leasing risk rather than current income; weak submarkets run higher. |
| Hospitality | 12% – 14% | Volatile revenue demands a wider margin. |
| Bridge and transitional | Tested at stabilization | The as-is debt yield is often far below the minimum; the exit debt yield governs. |
How it compares
| Metric | Influenced by interest rate? | Influenced by appraised value? |
|---|---|---|
| Debt Yield | No | No |
| DSCR | Yes, directly, through debt service | No |
| LTV | Indirectly, since rates move cap rates and values | Yes, entirely |
Common mistakes
- Dividing by property value instead of loan amount
- That produces the cap rate, not the debt yield. The denominator must be the loan.
- Using stabilized or projected NOI on a transitional asset
- Debt yield on a property that is 60% leased should be computed on in-place income. Using a pro forma figure defeats the purpose of a metric designed to exclude assumptions.
- Assuming a high debt yield means a good investment
- It measures the lender's protection, not the equity return. A high debt yield often signals a low-leverage loan on a property the lender views as risky.
Frequently asked questions
- What is a good debt yield?
- Minimum debt yields generally fall between 8% and 12%, with an average around 10%. Multifamily and industrial sit near 8%, office and retail near 10%, and hospitality at 12% to 14%.
- What is the difference between debt yield and cap rate?
- Both divide net operating income by a dollar figure, but by different ones. Cap rate divides NOI by the property's value and describes the asset's return. Debt yield divides NOI by the loan amount and describes the lender's return on its exposure.
- Why do lenders use debt yield instead of just LTV and DSCR?
- Because loan-to-value depends on an appraised value and DSCR depends on the interest rate and amortization schedule, both of which can make a weak property appear safe. Debt yield contains neither input, so it cannot be flattered by cheap debt or an optimistic valuation.
